PLANING- MACHINE.

SPECIFICATION forming part of Letters Patent. No. 296,562, dated April8, 1884.

Application filed December 10, 1883.

To aZZ whmn it may concern.-

Be it known that I, ELI B. HAYES, of Big Rapids, Mecosta county, in theState of Michigan, have invented new and useful Improvements inBlind-Slat Machines; and I do hereby declare that the following is afull and acsides are planed; third, in the overhanging i upper bed, allof which will be particularly described hereinafter with reference tothe ac companying drawings, wherein- Figure 1 is a perspective view ofmy machine. Fig. 2 is aplan of the same. Fig. 3 is a side elevation ofthe same. Fig. at is a plan of the adjustable bed. Fig. 5 is a sideelevation of the same. Fig. is a transverse Fig. 6 is a plan of theadjustable bed. several stages through which the slat passes in beingplaned.

The bed A is cast in one piece, with laterally projecting side pieces orribs, (4, to which the brackets 13 are bolted for the attachment andsupport of the spindles C for the edge-cutters D D. There are twofeed-rolls, E13, mounted onhorizontal shaft-s transverse to the machine,mounted in the ordinary housing, with regulatingscrews a to adjust therollers to materials of different thickness or to different pressures,as may be required. The two feedrolls are geared together.

0n the side of the machine opposite the feed roll gears I place upon theshaft of the lower feed-roll a gear-wheel, F, of twelve inches diameter,or thereaboutfand upon a stud, G, properly located below, I place apinion, H, in mesh with said gear-wheel F, to drive it. A pulley, I, andidler J are placed upon the same stud, G, and are connected with saidpinion, to transmit motion thereto. a

The brackets B are provided with handscrews L, whereby they may be movedout or in upon the ribs a, for the purpose of adjustingthe edge-planersto slats of different widths.

The cutter-spindles G are provided with pulleys K.

The slat is fed against a stationary gage, b,

(No model.)

1 on. one edge, and said gageis constructed to serve as a chip-breakerfor the edge-planer on that side. ing circular chipbreaker, d, andattach the same to the casting in which the box for the spindle O ismounted.

The upper and lower boxes of the upper planing-cylinder, M, are yokedtogether strongly, and by means of thehand-wheels and screws 0 they canbe raised and lowered and always kept in perfect line, thus giving theoperator all conveniences for making slats of any desired thickness. Thelower planing-cylinder, N, is placed near to the rear end of the frame,for reasons which will appear further on.

The overhanging bed 1? is a metallic frame or plate hinged to thebed-frame A by pivotpins 9 g at one end of said frame I, and located 011frame A between the planing-cylin ders M and N. Its omce is to hold andguide the slat while the planing-cylinder N is dress ing its under side,and to that end it is made adjustable up or down, and also adjustable tofit the transverse configuration of the upper surface of the planedslat, so that slats of various widths, thicknesses, or form may beprovided for. The frame Pis therefore provided at its free end with ayoke-plate, h, which is suspended from the free end of the bed by fourstud bolts, i, having rubber washersprings k and nuts Z,whereby thedistance between the yoke 71. and frame P may be adj ust-ed, but yetleft with slight elasticity. There are also two adjusting-screws, Q, bymeans of which the frame P and the yoke-plate h may be regulated. Theyoke-plate surrounds the planer-cylinder N, and one edge of the orificethrough which the cutters revolve acts as a chip breaker for saidcutters. The under surface of the frame P above the yoke h is alsoprovided with a set of changeable bars, q q, the lower surfaces of whichare made to conform to the planed side of the slat. For this purpose Iunite the bars 5; q q transversely by means of a strip of spring metal,0', so that changed by the adj ustingscrews t. The center bar q isbolted firmly to the frame I, and they may be removed and bars of otherpat tern substituted, if desired.

The main driving-shaft It of the machine is mounted in suitable boxesbeneath and trans- At the other side I place a yieldtheir relativepositions transversely may be IOO verse to the frame A. It is providedwith a large leading-pulley, S, at one end in plane with theplaner-pulleys T U. The main belt V, driven from the pulley W on theoverhead shaft, passes down, in the direction of its motion, around theleading-pulley S, and thence backward under and around the lowerplanerpulley, T, thence forward under and around the upperplaner-pulley, U, and back to drivingpulley WV, so that bothplaning-cylinders are driven directly by the same belt, and differencesin adjustment of said cylinders under their ranges of adjustment willnot change appreciably the traction of the belt. The shaft Ris alsoprovided with pulleys u uone on each side of the frame-from which beltsare led to the pulleys on the spindles O 0, respectively, to drive theedge-planers D D. There is also a pulley, y, upon the shaft R, fromwhich a belt is led to the pulley I, to drive the feed-rolls, as heretofore stated.

It is a well-known fact that edgingcutters for blind-slats wear down ornick in the center more rapidly than at the edges, because, the slatsbeing planed first on the sides, the ends of the edging-cutternecessarily overrun a little and have less work than at the center. Thisis a great practical difficulty present in every machine heretofore, sofar as I am aware, and entirely obviated by my improvement, whichrenders it possible to employ a regular beading-cutter, which planes theedge of the slat in the form shown in Fig. 7, and therefore encounteringequal labor at all parts of its cuttin ed e and avoidin nickin entirelHaving described my invention, I claim as new- 1. A blind-slat-planingmachine provided with bead edging planers and concave top and bottomside .planers, the edging-planers arranged to act in advance of the topand bottom planers, whereby the edging-planers do not become nicked byuse, asset forth.

2. The bed-frame A, provided with brackets for the shafts of the top andbottom planingcylinders, M N, the shaft R and leading-pulley Sintermediate said planingcylinders, and the driving-belt V, led oversaid pulley S and over the pulleys T U successively, as and for thepurpose set forth.

3. The planing-cylinders M. N, combined with the pivoted overhangingframe P, jointed to the frame A by pins 9 intermediate the planers, saidframe P-being provided with the yoke h and the adjustable bed-pieces q,substantially as and for the purpose set forth.

4. In a planing-machine fitted with planingcutters arranged to plane theunder side of the stuff as it passes the machine, and in combinationwith said under-side planer, an overhang ing frame, 1?, pivoted to themain frame, and provided with a planing-bed to hold the stuff againstthe action of the cutters, said overhanging frame being capable ofturning back 011 its pivots to expose said cutters and make them easilyaccessible for adjustment or sh arpening'.
